There was a joke at the time that although the National Security Agency had opened up in recent years and started taking their defensive role more seriously, the one aspect of cryptography which they would never discuss publicly was side channel attacks — and this itself constituted a side channel, revealing the…
Edit: Woah, this took off! If you want more details you can subscribe at the bottom of the post or on YouTube. I’m working on a more detailed highlights/commentary post and video. Previously: We got Claude Code playing Factorio, Towards beating Factorio autonomously, and Faketorio: an agent testbed I got GPT-5.6 Sol…
When your database CPU is at 100%, what is it actually doing? Memory stalls, CPU caches, and how radix partitioning makes GROUP BY faster.
The self-deleting VOLTA infostealer steals credentials, sessions, and cryptocurrency wallets. Then, it uses LLMs to profile victims and rank their most valuable assets.
Modern applications often spread state across a variety of systems: databases, caches, queues, data warehouses, search indices, and so on. Coordinating these systems is challenging: caches are often stale, the analytics platform might lag days behind the primary database, the search index might lose data, and…
I’ve been fascinated with local LLMs for a couple of years now. The better open weight models, including some that inference on regular, higher-end consumer hardware at tolerable speeds, are now reliable enough to handle simpler programming tasks. This requires a coding harness, but so far this year I’ve been…
Why do our grids show a brief spike in electricity demand every minute? A team led by Dirk Witthaut from Forschungszentrum Jülich has now demonstrated that this is due to regular power checks carried out by large-scale battery storage systems. These findings could help to make our electricity supply more robust, as…
By bypassing ChatGPT's sandbox and content security policy, our research team was able to take over anyone's account simply by sending them a link.
We have seen in a previous post that switch statements are more complex than they seem. The compiler is able to implement them as a decision tree (even though maybe it shouldn't). Is that everything it can do?
For a long time I have been a fan of minimalism in my physical life: have few physical possessions, and try to do more with less. Four years ago, I wrote this blog post describing what I had in the 40-liter backpack that I travel around with.
Over the past decade, the timing of PostgreSQL major releases has become very predictable: no earlier than the middle of September, and no l...
Our sans-IO WireGuard implementation in Rust, optimized for ease of use, security and performance through a parallel-friendly and idiomatic API.
A comprehensive overview of how email is encrypted, the benefits, and the trade-offs.
Jules Verne’s lost novel got the machines of 1960 right. He never imagined that Paris would keep its poets
tl;dr: You can now run many BeOS versions in the browser at Infinite Mac , my site where you can experience the Macintosh Cinematic Universe from 1984 to 2005. The installs are full peers to their Mac cousins: you can boot them instantly (large disks are streamed in), play around with pre-installed software from…
So today I reached a nice milestone in one of my projects: my work porting classic Mac OS to PowerPC systems with what I affectionately call ArtX chipsets (Nintendo GameCube, Wii, eventually Wii U; the GameCube’s Flipper integrated chipset was very much designed by ArtX as it was effectively finished when ATI acquired…
OpenAI CEO Sam Altman claimed in a recent podcast discussion that it's "terrible" for everyday people to own DRAM that data centres can use.
When AI handles 95% of your incident response, do you get worse at handling the 5% that actually matters?
For most of the past two decades, the code forge has been where projects live: where code is hosted, where changes are reviewed, and where contributors find each other. Forges offered convenience in exchange for centralisation.
Join us to explore the ups and downs over twenty years spent running a small bootstrapped UK SaaS business.
Yesterday, Anthropic were compromised and used to stage a global supply chain attack.
In my previous blog posts, Azure’s Weakest Link? and Azure’s Weakest Link - Full Cross-Tenant Compromise, I gave an overview of the severely insecure architecture behind API Connections in Azure, a part of Azure Logic Apps, and an instance of a full cross-tenant compromise using these inherent flaws. Now I am back…
Phorion has detected a backdoor in the official Claude Code for VS Code extension bundle on the Cursor Marketplace that drops a persistent SSH backdoor across macOS, Linux, and Windows. This write-up …
Swarms of Claude and GPT agents in Minecraft and Mindustry.
I've done a lot of activism for software freedom, over the years. At first it was purely for software freedom and related topics, (such as security, autonomy and privacy) but eventually this has evolved into something more holistic. I believe that the software I use should be held to higher ethical standards than only…
Look, I really didn’t want to like Duet. I don’t want to be an Anthropic fanboy and it annoys me when they do things better than the competition. But they have done it again.
Among the personalities honoured by the President of the Czech Republic on the occasion of the national holiday on 28 October this year are two graduates of Brno University of Technology. Tomáš Mikolov, a renowned expert in artificial intelligence, and Filip Maleňák, creator of the Záchranka mobile app, received state…
Search was 49.7% of Alphabet's revenue in Q3 2026, down from 62% in early 2019, as Google Cloud grew much faster. Every quarter since 2018, from Alphabet's earnings releases.
NVL72 puts all 72 GPUs in a rack on one NVLink fabric, but only rack-local jobs get the speedup. How SkyPilot keeps multi-node training and inference on NVLink with topology-aware placement, in-place recovery from GPU failures, and automatic defragmentation.
